I have NO idea how to do this! any help is great!

A car of maass 1330kg is traveling at 28m/s. The driverapplies the brakes to bring the car to a rest over a distance of 79m. Calculate the retarding force acting on the car.

From this i can see that it gives me the

Mass:1330kg

the inicial velocity: 28m/s

and the distance: 79m

i'm trying to find the force, but i can't think of a formula using the known variables!!
